The beauty industry produces an estimated 120 billion units of packaging every year, the majority of which is plastic and the vast majority of which is not recycled. Plastic-free beauty has become a significant marketing message in response, but “plastic-free” claims vary enormously in what they actually mean. Understanding the difference between packaging that genuinely reduces environmental impact and packaging that just shifts the problem is useful whether you’re choosing products for yourself or evaluating brand claims.
What “plastic-free” actually means (and doesn’t)
There is no regulated definition of “plastic-free” in cosmetics in most markets. This means brands can use the term relatively freely. Some common ways the claim gets stretched:
Replacing primary packaging with glass while keeping plastic pump mechanisms, plastic safety seals, and plastic shipping materials. The bottle itself is glass; the overall packaging system still involves significant plastic.
Using “bio-based” plastics made from plant starches or sugars rather than petroleum. These materials are often chemically identical to conventional plastics in their end-of-life behaviour, meaning they don’t biodegrade in landfill or ocean conditions despite their plant origin.
Switching to paper outer packaging while keeping plastic inner packaging. This improves perception but may not reduce total plastic content significantly.
Genuine plastic-free packaging at a product level typically means glass or aluminium primary containers with metal or cork closures, paper or card outer packaging, and no plastic components in the pump, seal, or shipping materials. This is achievable but involves real formulation and logistics constraints.
Why formulation and packaging are connected
Switching from plastic to glass or aluminium isn’t only a packaging decision. Many product formulations are specifically developed around plastic containers. Certain preservative systems are designed for the oxygen permeability of plastic. Some actives react with metal. Pump mechanisms in fully metal or glass configurations cost more and are less widely available.
Solid format products, bar soaps, solid shampoos, concentrated serums in tablet or powder form, avoid the packaging problem more elegantly than just changing the container material. Removing water from a formula reduces the weight and volume shipped, which lowers transport emissions, and often eliminates the need for preservatives designed to prevent microbial growth in water-based products. A solid shampoo bar typically requires minimal packaging, is more concentrated than liquid equivalents, and often outlasts the equivalent liquid volume.
Recycling reality
The recycling claim on beauty packaging is frequently overstated. In most developed markets, recycling infrastructure for cosmetic packaging is limited because:
Most cosmetic bottles are mixed-material, meaning a plastic bottle with metal closure and plastic pump is difficult to disassemble for recycling. Collection systems typically only accept single-material items sorted to a specific plastic type.
Contamination from residual product makes many bottles non-recyclable in standard streams. Rinsing containers before recycling is necessary but rarely done.
Small containers, most cosmetic tubes and bottles fall below the size threshold for most sorting machinery, which means they fall through sorting processes.
Take-back schemes run by brands like those offered by Terracycle partners are more reliable than kerbside recycling for cosmetic packaging, but they require the consumer to actively send items back.
Refillable packaging is probably the most practical solution from a lifecycle perspective. A glass or aluminium bottle designed to be refilled requires manufacturing investment once and generates packaging waste only from the refill itself, which can be minimal.
What small natural cosmetics brands can realistically do
Small brands producing lower volumes face different constraints than large corporations. They often can’t access recycled plastic streams at the minimum order quantities that make them economically viable. Custom glass bottles require significant minimum orders. But small scale also brings some advantages: more flexibility to experiment with format, stronger relationship with customers who understand and support the values behind the packaging choices, and less inertia from legacy product lines.
Brands like HOIA, making handmade natural cosmetics in small batches on Saaremaa island, make practical choices about packaging that reflect both quality and reduced environmental footprint where possible. The combination of small batch production, natural ingredients, and considered packaging materials is a different model to industrial cosmetics, and the environmental calculus looks different across the full product lifecycle.
What you can actually do as a consumer
Buy concentrated or solid formats where they exist and work for you. One less water-heavy product shipped in a large plastic bottle is a more direct intervention than buying an identically formulated product in glass.
Use products fully before replacing them. The environmental cost of a product is predominantly in its manufacture. A half-used product thrown away is wasteful in a way that careful packaging choices don’t compensate for.
Favour brands with genuine transparency about their packaging supply chain rather than those with front-label claims and no specifics. A brand that tells you what percentage of their packaging is recycled, what their refill options are, and what they’re working toward is more credible than one that says “eco-friendly” with nothing to back it up.
Reducing consumption overall outperforms material switching as an environmental strategy. A ten-product routine generates more packaging waste than a four-product routine regardless of what the packaging is made from.
